我需要为改造2.0.0-beta2库发出的每个请求添加一个查询参数。我找到了这个适用于改造1.9的解决方案，但是如何添加最新的库版本？RequestInterceptor

我的界面：

@GET("user/{id}")
Call<User> getUser(@Path("id")long id);

@GET("users/")
Call<List<User>> getUser();

客户：

Retrofit retrofit = new Retrofit.Builder()
                    .baseUrl(BASE_URL)
                    .addConverterFactory(GsonConverterFactory.create())
                    .client(CLIENT)  // custom OkHTTP Client
                    .build();
service = retrofit.create(userService.class);

为了完整起见，以下是使用 OkHttp-Interceptor 向每个 Retrofit 2.x 请求添加参数所需的完整代码：

OkHttpClient client = new OkHttpClient();

client.interceptors().add(new Interceptor() {
    @Override
    public Response intercept(Chain chain) throws IOException {
        Request request = chain.request();
        HttpUrl url = request.url().newBuilder().addQueryParameter("name","value").build();
        request = request.newBuilder().url(url).build();
        return chain.proceed(request);
    }
});

Retrofit retrofit = new Retrofit.Builder()
        .baseUrl("...")
        .client(client)
        .build();

现在改造已经发布了2.0.0，这是我的解决方案：

OkHttpClient client = new OkHttpClient.Builder()
        .addInterceptor(new Interceptor() {
            @Override
            public Response intercept(Chain chain) throws IOException {

                String uid = "0";
                long timestamp = (int) (Calendar.getInstance().getTimeInMillis() / 1000);
                String signature = MD5Util.crypt(timestamp + "" + uid + MD5_SIGN);
                String base64encode = signature + ":" + timestamp + ":" + uid;
                base64encode = Base64.encodeToString(base64encode.getBytes(), Base64.NO_WRAP | Base64.URL_SAFE);

                Request request = chain.request();
                HttpUrl url = request.url()
                        .newBuilder()
                        .addQueryParameter("pageSize", "2")
                        .addQueryParameter("method", "getAliasList")
                        .build();

                request = request
                        .newBuilder()
                        .addHeader("Authorization", "zui " + base64encode)
                        .addHeader("from_client", "ZuiDeer")
                        .url(url)
                        .build();

                Response response = chain.proceed(request);
                return response;
            }
        }).build();


Retrofit retrofit = new Retrofit.Builder()
        .baseUrl(ApiConstants.API_BASE_URL)
        .client(client)
        .addConverterFactory(GsonConverterFactory.create())
        .addCallAdapterFactory(RxJavaCallAdapterFactory.create())
        .build();

mRestfulService = retrofit.create(RestfulService.class);
